I have Nero 5.5. on an Acer CD writer I think the spec is 40/20/12. I don't have another CD rom installed and the mobo is pc chips integrated board. It has 256M of memory. I simply cannot get nero to write. It reads disks ok, plays cds ok but can't get it to write. I have visited nero's home page but their support is rubbish, I cannot find out anything.
